logging levels configurable at runtime (log.level in the api config)
optional logging to a file (log.file in the api config)
a compile time switch for debug messages (LSL_DEBUGLOG)
log messages include a name for the originating thread
optional printing of the stacktrace on abort (or segfault)
An example log output looks like this

The only minor setback is the C++11 requirement (i.e., MSVC 2015), so it'd have to wait for 1.14.
This PR adds a logging library to liblsl.
